Tips for trouble shooting
Delegate unit does not work
Check if the system cable between power supply and delegate unit or central
unit and delegate unit is defective or if the system cable has been pulled out.
Check if the central unit or the power supply are connected to the mains
and if they are turned on.
Within a cable string, only the dele-
gate units from a certain unit on-
wards are flashing
The flashing delegate unit doesn’t contain any data. Possible causes:
y
The first flashing delegate unit in the string is defective. Replace the
defective unit.
y
The system cable in front of the first flashing delegate unit is defective.
Replace the defective system cable.
y
The delegate unit connected in front of the flashing unit is defective
(this unit contains data but does not sent the data). Replace the
delegate unit connected in front of the flashing delegate unit.
y
Within the string, a defective power supply is connected in front of the
flashing delegate unit. Replace the defective power supply.
To eliminate the problem, first replace only one of the components
(delegate unit, cable or power supply). If the problem persists, replace the
next component and so on.
After turn-on, a complete
cable string continues flashing
The complete cable string cannot receive any data. Possible causes:
1. The system cable between the central unit and the first delegate unit
in the string is defective. Replace the defective system cable.
2. The first delegate unit in the string is defective. Replace the first
delegate unit.
3. The first component in the string is a defective power supply. Replace
the defective power supply.
Check and replace the components in the order described above. Once a
components has been replaced, the cable string should receive data again.
If the problem persists, replace the next component and so on.
The chapter “System diagnosis” provides further information on trouble
shooting.
